1 is a cross-sectional view illustrating a bezel structure of a display device according to embodiments of the present invention.

Referring to FIG. 1, a bezel structure 100 of a display device may include an ultraviolet curing resin layer 110, ink layers 120 and 125, a transparent resin layer 130, and a superstructure 140. The superstructure 140 may include a polyethylene terephthalate (PET) film 150 and a protective window 180.

In the display device, the ultraviolet-curable resin layer 110 may be formed entirely on the lower panel to adhere the lower panel and the protection window. This will be described in detail with reference to FIGS. 4 and 5. FIG. In addition, the ultraviolet-curable resin layer 110 can improve the brightness, transmittance, reflectance, and visibility of the display device. The bezel region may be formed in a partial region (i.e., an outline of the display region) on the ultraviolet curable resin layer.

The ultraviolet curable resin layer 110 may include an optical bonding resin to perform the function of the adhesive layer. That is, the ultraviolet-curable resin layer 110 may be formed of a material exhibiting adhesiveness when cured by ultraviolet irradiation in a resin state. The ultraviolet-curable resin layer 110 may be formed by the reaction of a photopolymerization initiator and a monomer (or an oligomer). The photopolymerization initiator is irradiated with ultraviolet rays to generate radicals, and the radical polymerizes with the monomer to form a macromolecular polymer having adhesiveness. In order to form the ultraviolet curing resin layer 110 by curing the resin, the applied resin must be irradiated with a sufficient amount of ultraviolet (UV). However, in the case of a shaded area, the ultraviolet ray is not irradiated properly, and the ultraviolet ray hardening resin layer 110 may be partially uncured. That is, the uncured portions can be mainly generated in the bezel region. The uncured portions may have monomers as they are.

The ink layers 120 and 125 may implement the color represented by the bezel structure 100. The ink layers 120 and 125 include a nonvolatile solvent and may be formed on the ultraviolet curable resin layer 110. [ The ink layers 120 and 125 may be composed of a non-volatile solvent, a resin, and a pigment. When a volatile solvent is used in the drying process after the ink layers 120 and 125 are formed, voids 135 and 136 may be formed in the ink layer by evaporation of the volatile solvent. Therefore, according to the embodiment of the present invention, a non-volatile solvent can be used as a solvent constituting the ink layers 120 and 125. [ Since the nonvolatile solvent hardly evaporates due to the drying, the voids 135 and 136 formed in the ink layers 120 and 125 can be minimized. Non-volatile solvents may include cyclohexanone, isophorone (IPR), and the like. However, this is merely an example, and non-volatile solvents are not limited thereto. The pigments constituting the ink layers 120 and 125 can determine the overall color of the bezel structure 100. For example, the pigment may comprise a material such as carbon black, titanium oxide (TiO ₂ ), zinc oxide (ZnO), lithopone or lead white. Carbon black can be used to represent a black-based color in the bezel structure 100. Titanium oxide, oxidized silicon, ritofone, and white can implement a white bezel structure (100). However, this is only an illustrative example, and the pigment is not limited thereto. Depending on the embodiment, a wide variety of pigments may be included to achieve various colors.

The voids 135 and 136 may be generated by evaporation of the solvent contained in the ink layers 120 and 125 or generation of gas upon chemical reaction. The monomers present in the uncured portions of the ultraviolet curable resin layer 110 may penetrate the voids 135 and 136 and cause discoloration of the bezel region. Thus, it is necessary to prevent the monomer from penetrating into the pores 135, 136 to prevent discoloration of the bezel region. At this time, the transparent resin layer 130 can prevent the monomer from penetrating into the gap 136.

The transparent resin layer 130 may be disposed in the middle of the ink layers 120 and 125 to prevent the monomer (i.e., the uncured ultraviolet curable resin) from penetrating into the void 136 generated in the ink layer 125. [ In one embodiment, the transparent resin layer 130 may comprise a transparent polymeric resin. For example, the transparent polymer resin may include a resin such as acrylic urethane, epoxy, or polyester. However, this is merely an example, and the transparent polymer resin is not limited thereto.

The transparent resin layer 130 may serve as a barrier to prevent the monomer present in the ultraviolet curable resin layer 110 from penetrating the transparent resin layer 130. 1, the monomer can not penetrate into the gap 136 of the ink layer 125 formed on the transparent resin layer 130. Therefore, the transparent resin layer 130 can prevent the discoloration phenomenon of the bezel region, which occurs when the monomers penetrate the void 136.

The superstructure 140 may be formed on the ink layer 125. In one embodiment, the superstructure 140 may include a protective window formed on the PET film 150 and the PET film 150. The PET film 150 has a strong strength, a low heat shrinkage ratio, good heat resistance characteristics, excellent electrical insulation properties, excellent durability against chemicals, and low gas permeability. Therefore, the physical and chemical reliability of the bezel structure 100 (and furthermore, the display device) can be improved.

The upper structure 140 may further include a patterned pattern layer 160 by UV molding a polymeric resin on top of the PET film 150. In one embodiment, The pattern formed on the pattern layer 160 may include a wavy pattern, a lattice pattern, or the like. Therefore, the pattern layer 160 can provide a user with aesthetic effect by forming various patterns in a bezel region having only a simple color. However, the pattern of the pattern layer 160 is not limited to a wavy pattern or a lattice pattern. According to an embodiment, a pattern layer having various patterns can be formed. The process of forming the pattern layer 160 will be described in detail with reference to FIG. 2D.

In one embodiment, the superstructure 140 may further comprise an oxide layer 170 comprised of a plurality of oxides having different refractive indices over the pattern layer. The oxide layer 170 may be formed by alternately stacking an oxide having a high refractive index and an oxide having a low refractive index. Due to the difference in the refractive index, the bezel region may be illuminated by diffused light, thereby realizing the effect of the bezel region shining. Thus, the oxide layer 170 can provide aesthetic effect to the user. The oxide having a high refractive index includes titanium oxide (TiO ₂ ), and the oxide having a low refractive index may include silicon dioxide (SiO ₂ ). In the case of a wavelength region of 630 nm corresponding to the visible light region, the refractive index of titanium oxide is about 2.49 and the refractive index of silicon dioxide is 1.46. However, the oxides constituting the oxide layer 170 are not limited thereto. According to an embodiment, the oxide layer may comprise a plurality of oxides having a refractive index difference of more than a certain standard.

The protective window 180 may be formed on the PET film 150. The protection window 180 is formed on the uppermost portion of the bezel structure 100, so that the lower structure can be protected from external shock, moisture, and the like. In one embodiment, the PET film and the protective window 180 may be glued with an optically clear adhesive (OCA). Therefore, transparency of the bezel structure 100 can be maintained. Also, in one embodiment, the protection window 180 may be comprised of a glass window.

As described above, the bezel structure 100 of the display device according to FIG. 1 can minimize the occurrence of voids during the drying process of the ink layer 120 by using a nonvolatile solvent for the constitution of the ink layer 120. [ Also, by arranging the transparent resin layer 130 in the middle of the ink layer 120 for determining the color of the bezel region, it is possible to prevent the monomer from penetrating into the voids formed on the transparent resin layer 130. Therefore, it is possible to prevent the discoloration phenomenon of the bezel region caused by penetration of the monomer into the pores.

2A to 2F are cross-sectional views illustrating a process of forming the bezel structure of FIG.

Referring to FIG. 2A, an ink layer 120 for determining the color of a bezel region may be formed on an ultraviolet-curing resin layer 110 to be cured by ultraviolet irradiation. In the display device, the ultraviolet-curable resin layer 110 may be formed entirely on the lower panel to adhere the lower panel and the protection window. This will be described in detail with reference to FIG. 4 and FIG.

The ultraviolet-curable resin layer 110 may be formed of a material exhibiting adhesiveness when cured by ultraviolet irradiation in a resin state. The ultraviolet-curable resin layer 110 may be formed by the reaction of a photopolymerization initiator and a monomer (or an oligomer). The formation of the ultraviolet-curable resin layer 110 has been described above with reference to FIG. 1, and a duplicate description thereof will be omitted.

The ultraviolet curable resin layer 110 may not be irradiated with ultraviolet light and may be partially cured. The uncured portions may have monomers as they are. These monomers can freely penetrate into the upper region or the like. In particular, such a monomer may penetrate into the voids 135 formed in the upper ink layer 120 to cause a discoloration phenomenon.

The ink layer 120 may implement the color represented by the bezel structure 100. The ink layer 120 includes a nonvolatile solvent and may be formed on the ultraviolet curable resin layer 110. [ The ink layer 120 may be composed of a non-volatile solvent, a resin, and a pigment. Since the nonvolatile solvent hardly evaporates due to the drying process of the ink layer 120, the voids 135 formed in the ink layer 120 can be minimized. However, since the formation of the ink layer 120 has been described above, a repetitive description thereof will be omitted.

2B and 2C, the transparent resin layer 130 may be formed on the ink layer 120, and the ink layer 125 may be formed on the transparent resin layer 130 again. The transparent resin layer 130 may serve as a barrier to prevent the monomer present in the ultraviolet curing resin layer 110 from penetrating the transparent resin layer 130. Accordingly, the monomer can not penetrate into the gap 136 of the ink layer 125 formed on the transparent resin layer 130. Monomers may penetrate into the voids 135 of the ink layer 120 disposed under the transparent resin layer 130, so that discoloration may occur. However, the portion where the discoloration occurs is not visually recognized by the ink layer 125 disposed under the transparent resin layer 120. Therefore, discoloration of the bezel region can be prevented by the transparent resin layer 130 disposed in the middle of the ink layers 120 and 125. [

In one embodiment, the transparent resin layer 130 may comprise a transparent polymeric resin. However, since the formation of the transparent resin layer 130 has been described above, a duplicate description thereof will be omitted.

Referring to FIG. 2D, a PET film 150 having a pattern layer 160 formed thereon may be disposed on the ink layer 125.

The pattern layer 160 is formed by applying an ultraviolet ray hardening resin on the PET film 150. The ultraviolet ray hardening resin is patterned through a light transmitting tool (or a mold) having a pattern formed thereon, .

The pattern may include a wavy pattern or a lattice pattern. Accordingly, the pattern layer 160 can provide aesthetic effect to the user by forming patterns of various shapes in a bezel region having only a simple color by the ink layers 120 and 125. However, since the PET film 150 has been described above, a duplicate description thereof will be omitted.

Referring to FIG. 2E, an oxide layer 170 composed of a plurality of oxides having different refractive indexes may be disposed on the PET film 150 on which the pattern layer 160 is formed. The oxide layer 170 may be formed by alternately stacking an oxide having a high refractive index and an oxide having a low refractive index. Due to the difference in the refractive index, the bezel region may be illuminated by diffused light, thereby realizing the effect of the bezel region shining. Thus, the oxide layer 170 can provide aesthetic effect to the user.

Referring to FIG. 2F, a bezel structure 100 of the display device may be formed by disposing a protection window 180 on the oxide layer 170. The protective window 180 may be adhered to the PET film 150 including the oxide layer 170 and the pattern layer 160 by an optical transparent adhesive. In one embodiment, the protective window 180 may be formed of a glass window and formed transparently. The protective window 180 may protect the underlying structure from external shock, moisture, chemical action, and the like. In addition, the protective window can be formed integrally with the display area of the display device as well as the bezel area.

3, the bezel structure 300 of the display device may include an ultraviolet curable resin layer 310, an ink layer 320, a transparent resin layer 330, and a superstructure 340. In one embodiment, the superstructure 340 may include a PET film 350 and a protective window 380.

The upper structure 340 includes a pattern layer 360 formed by patterning a polymer resin with ultraviolet molding and an oxide layer 370 composed of a plurality of oxides having different refractive indexes is formed on the pattern layer 360 . Further, in one embodiment, the PET film 350 and the protective window 380 are bonded with an optical transparent adhesive, and the protective window 380 may be composed of a glass window. However, since the ultraviolet curable resin layer 310, the PET film 350, the pattern layer 360, the oxide layer 370, and the protective window 380 have been described above, a duplicate description thereof will be omitted .

The transparent resin layer 330 may be disposed on the ultraviolet curable resin layer 310. That is, the transparent resin layer 330 is disposed under the ink layer 320 to prevent the uncured ultraviolet curable resin (i.e., monomer) from penetrating into the void 335 generated in the ink layer 320. Therefore, the transparent resin layer 330 can prevent the discoloration phenomenon of the bezel area that is generated by the penetration of the monomers into the void 335. In one embodiment, the transparent resin layer 330 may comprise a transparent polymeric resin.

The ink layer 320 may implement the color represented by the bezel structure 300. The ink layer 320 includes a nonvolatile solvent and may be formed on the transparent resin layer 330. [ Since the nonvolatile solvent hardly evaporates by the drying process, the voids 335 formed in the ink layer 320 can be minimized.

However, since the transparent resin layer 330 and the ink layer 320 have been described above, a duplicate description thereof will be omitted.

As described above, the bezel structure 300 of the display device according to FIG. 3 can minimize the occurrence of voids during the drying process of the ink layer 320 by using the non-volatile solvent for the constitution of the ink layer 320. [ In addition, by arranging the transparent resin layer 330 at the lower part of the ink layer 320 for determining the color of the bezel area, it is possible to prevent the monomer from penetrating into the void generated in the ink layer 320. Therefore, it is possible to prevent the discoloration phenomenon of the bezel region caused by penetration of the monomer into the pores.
